The layout theta determines the accuracy of the Barnes–Hut approximation computation; larger values increase the speed of the
simulation but lower its accuracy. When theta is 0
, the algorithm becomes a
direct-sum algorithm.
To change the layout theta setting, navigate to the Marks menu, and
change value for Layout theta option. The default setting is
0.8
.
Compare the appearance of a visuals with layout theta settings of 0
,
0.8
, and 1
